The document discusses trends in US oil and natural gas production from shale and tight resources. It notes that 6 key shale plays account for nearly 90% of domestic oil production growth and all natural gas production growth in recent years. Production has grown due to increased drilling efficiency rather than more rigs. The Bakken and Eagle Ford plays drive most oil growth while the Marcellus drives natural gas growth. Abundant shale gas leads to lower natural gas prices and increased domestic consumption, particularly in manufacturing and transportation. The US is projected to become a net exporter of natural gas by 2025. Rising tight oil and offshore production could push US crude oil output close to historical highs.
